Toall whom it my concerns Be it known that I, Fnmonron Anew Rrcn'rnn, asub'ect of the German Emperor, andresident 0 Rudolst'adt, Germany, haveuseful Improvementsin .Toy Bridges. of which; the following is a s'ecification;

My 'inventlon relates to toybridges and has for its object to provide abridge composed of several parts which may be readily assembled andputtogether in a simple manner without the aid of screws, splints, pegs minvention,=Fig. 3 is asimilar view of view of a bridge section ,'andFigs struction shown in still another form, Fig. 4. is a perspective 5and 6 are perspective views of two additional forms of my invention.

In the drawin s a represents preferably U-shaged bows o angular crosssection arrange as to form substantially a foundation on which thebridge isconstructed and supported. In the lparticular forin of conig.1, the bridge girders c are formed with angular flanges which ex:

tend. lengthwise thereof at opposite edges and each of which is providedwith an aperture located nearits' opposite ends it being understood thatthe apertures p of each flange at each end, are" m alinement with eachother." These apertures 2 are of a size and shape to be readily slippedover the upwardly extendingmembers of the how a, as clearly shown 1nFig.1. "Each of said, 'rders-c is further provided near itsoppos1te'ends with lugs engageithe upwardly extending members of thebowsa, when the parts are assembled and revent accidental displacementthereof. bridge section 0 is supported on the horizontal members of thebows a. in the finished structure. 'To assemble this form a of bridgethe of the girders be connected and asv be had to the accompanyb v 'thegirders 0 are slip improved bridge construction,

said girders may be the lugs q or supporting "said g which fr'ictionally-tion on' the bows the bows a and the bri ge section '0 is set u on hehonzontal portion of said bows a. T e' apertures p cooperating with theup.--'

'ght members of the bows prevent any ative a vertical one.

are slipped over the 'right me'iilbers of} movement of the girders otherthan In the f rm of my invention shown Fig. 2,'each bow a is providedwith resilient members I) suitably secured .in' position thereon andextending parallel with and a'd jacent to the upright members of saidbow.

In this illustration, the girders c are formed with flanges similar tothe longitudinal flanges on the girders shown in Fi 1, with theexception t at said flanges in ig. 2 ter minate short of the ends ofsaid irders.

The said girders further have their endspre'ferably turned or bent toform-vertical flanges f, which,

In assemblingthisform of my invention,

ed bet-weenthe right members on the ws a and the resilit with thehorizontal flanges hereinbefore referred to, form recesses --e'.

ent members b in, which position they are firmly held a ainstdisplacement by the pressure of'sai resilient members. Lengthwisemovement of said girders c, is prevented through the medium of theflange fund the horizontal flanges'which engage'opposite edges of. theupright -members of the.

bowsa. In, other words the said upright members extend between theflanges f and the ends of the respective horizontal flanges into therecesses e and secure the said g1r-' ders in position. In. this form'thebridge section 0 maybe supported directly on the horizontal membersof'the bows a which in this caseare' provided with a reinforcing pieceas shown in Fig.-

rovided with lugs similar to bridge section'o. r

In Fig. 3 the girders c' are constructed in thesaine manner as thegirders c in Fig. 2 and are secured 'to the bows'a. by means 0 Asimilar'resilient devices b.-' The bows a in 2', or if desired; the

this form, however, are made with upright members of increased len h andare-,pro-

vided with additional resi ient holding devices b for the accommodationof railings d. The said railings are secured in ime'mbersb' and theuprightmembers of the.

between the res: ientbows a and set upon theupper edgeof the t of thesegirders c'. Lengthwise movem tier railings is also prevented by means ofes words the recesses e, in the same manner as described with regard tothe girders 0 in Fig.

the girders '0 near the upper edges necessary thereof and serve tosupport the bridge sec tion 0. i

The construction shown in Fig. 5 differs from those already describedinv that the u pr ght members of the bows a are provided with spacedprojections g which cooperate been substituted for the projections g ofFig. 5 and slots is have been substituted for he slots 2', otherwisethis form of my invenion is-the same as thegt shown m Fig. 5.

In Fig. 5 the girders and'reilings are prevented from slippin from theprojections c v by means of the heads thereof, the shanks of saidprojections extending through the reduced portions 1 6 the upwardly ofsaid slots, while in Fig. extendi. 5 portions of the such di p :icementof the girders and railin s. it is to be understood that-the heads ofthe pro-' 'ections c are of size to easily slipped through theenlargedpins h prevent portions of. the slots i but are too large to passthroughthe reduced portion thereof. films to said rders it is first toraise 1 to ing the enlarged portions ofthe slots 11 and the heads of thelugs lo into registry with each other sitter t willthus be that in theforms of my invention, the scverelpar'ts constituting the finished,structure, are all easily and f and horizontal flanges or in other 2.Pins or projections m are located.

3 tending flanges at opposite edges.

flanges terminate short of the ends of the lich said girders may beremoved by a smple lateral movement.

quickly assembled without the aid of screws i or other similar fasteningdevices,'and when so assembled, are firmly held in position againstaccidental displacement or dislocation. ,In order to prevent the bridgesection 0 from slipping from the-various supporting mediums, that isthelugs g and projections m and n the said bridge section 0 is formed withlongitudinal downwardlyex- These bridge section 0 and the ends thereofabut against the said lugs g and projections m I and n so thatlengthwise movement of the bridge section 0 is absolutely prevented.

' Variousfchanges the specific constructlonsshown and described may bemade.

withinthe scope of the volaims without departing from the spirit of myinvention.

I claim:

1. A toybridge comprising supporting end members, removable side membersslidably mounted thereon and a bridge section removably connectedtherewith. I

2. A toy bridge comprising U-shaped end. members, removable sidemembersslidably mounted on the upright portion of said end members and a bridgesection removably connected therewith.

3. A toy bridge comprising side members provided with openings,U-shaped' end mem bers adapted to extend into said openings and a bridgesection connected with said end members. y

4. A to'y'bridge comprising side members,

flanges extending lengthwiseof-said side members and each. rovided withopenings,

U-shaped end mem ers ,sdapted to extend into seid openings, projectionson said side members adapted to frictionallyengage said end members anda bridge section removably connect-ed with sai-d endmembers,
